Subject: No sound after returning from suspend-to-ram
Date: Wed, 23 Sep 2009 21:20:19 +0300	[thread overview]
Message-ID: <4ABA66E3.7090202@pardus.org.tr> (raw)

Hi,

A user complains that after returning from suspend-to-ram, he isn't able
to get any sound from his laptop until rebooting. I delayed reporting
this one because I once thought that it may be related to Pulseaudio or
some kind of mixer level problem but now I tried to suspect the kernel
and the drivers as well.

This is 2.6.30.5 with alsa-* 1.0.21a. I have dmesg and alsa-info outputs
before and after s2ram:

dmesg before s2ram:
  http://bugs.pardus.org.tr/attachment.cgi?id=4454

alsa-info before s2ram:
  http://bugs.pardus.org.tr/attachment.cgi?id=4455

dmesg after s2ram:
  http://bugs.pardus.org.tr/attachment.cgi?id=4456

alsa-info after s2ram:
  http://bugs.pardus.org.tr/attachment.cgi?id=4457


Note that a traceback is dumped in dmesg during resume. Maybe it will
give a clue about the problem, dunno.


And there's something like

hda_codec: invalid CONNECT_LIST verb 12[2]:2100

in regular dmesg output, i wonder what does that mean too.

Any ideas?
Thanks,

Ozan Caglayan
